Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2017-1071)

The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2017-1071 advisory.

A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. (CVE-2016-8650) A flaw was found in the Linux kernel's implementation of setsockopt for the SO_{SND<pipe>RCV}BUFFORCE setsockopt() system call. Users with non-namespace CAP_NET_ADMIN are able to trigger this call and create a situation in which the sockets sendbuff data size could be negative. This could adversely affect memory allocations and create situations where the system could crash or cause memory corruption. (CVE-2016-9793) A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory. (CVE-2017-2618) The keyring_search_aux function in security/keys/keyring.c in the Linux kernel through 3.14.79 allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a request_key system call for the 'dead' type.(CVE-2017-6951)

'kernel' package(s) on Huawei EulerOS V2.0SP1.

Checks if a vulnerable package version is present on the target host.

Please install the updated package(s).
